Precedence: bulk

Situation in Question:
        root@SomeHost having a Script running off cron which tries to
        (ufs)dump Stuff to SomeUser@TapeHost. SomeUser@TapeHost having
        restricted Shell, .rhosts, owns Tape Devices, all the Jazz.
        Everything fine and dandy with .rhosts reading "SomeHost root"
        on a 4.x Machine, but on 2.4, .rhosts all of a Sudden needs
        to be "SomeHost SomeUser", though SomeUser@SomeHost doesn't even
        exist.

Solution:
        2.4 ufsdump is messed up. (Read: The Problem is limited to this
        one Executable. Phew! ;-) If running as root, its hardcoded
        rsh Implementation will identify the dump'ing User as
        SomeUser@SomeHost, rather than root@SomeHost. Possibilities:
        1) Live with the "strange" .rhosts (which I'll do right now)
        2) Run dump as non-root (involves chown'ing raw Disk Devices ...)
        3) Patch 102680-04 might fix it (I'll check)
        4) Avoid the ufsdump rsh Implementation altogether (like in
           dump f - | rsh dumphost cpio or whatever. I'ld like to
           get ufsdump switched to ssh, but that's a Bit too messy
           to do it from Scratch myself ;-)

Thanks again,
